We decided on a last minute trip to WDW last Memorial Day weekend. I called MS about 3 or 4 weeks out, and was not able to get either a studio or 1BR at VWL, which was where we prefer to stay for very short visits. We ended up using points to stay at AKL. Parks were crowded on that Sunday, but not terrible. It was very hot, so we ended up spending Memorial Day, itself, at Typhoon Lagoon.
